Hi folks,
How do I get current information from ACS 5.3 about TACACS+ transactions per second (tps)? I can only see T+ authentications per day summaries. I need this to size for a migration to ISE for T+ only deployment and the ISE team has tps numbers to size a deployment with.
Solved! Go to Solution.

Hi,
Please see the catalog reports available for ACS 5.3.
Essentially you need to combine all the three reports ( authentication, authorization and accounting) for the ACS server and aggregate it for say 8hrs(working time) to get the TACACS+ TPS.
Thanks

Krishnan,
Is this the best process for ACS 5.8 as well?

Just to verify my understanding, if below data is for one day (24 hrs) from existing ACS:
Total Authentication messages (Pass+Fail) = 250000, Total Authorization messages = 370000 and accounting messages = 118000 then TPS would be:
(250000+370000+118000) / (24X60X60) = 8.54 TPS
Is this correct way to find out TPS?
Customer currently has 12 ACS instances. But using above calculation and ISE TPS handling capacity, it comes out to be only 2 ISE PSNs (considering HA).
Just want to double sure.
